Abstract

Objective: to compare the long-latency auditory potentials in children with bilateral sensorineural hearing losses from mild to moderately severe with those obtained in normal-hearing children of the same age group. Methods: cross-sectional clinical study, consisting of two groups: control group - Group of 10 normal-hearing children, 6-13 years of age, of both genders, Research Group - Group of 10 children with sensorineural hearing loss of mild to moderately severe bilateral symmetry between the ears, aged 6 to 13 years of age, of both genders, with no prior experience with any type of sound amplification device. Will be recorded Auditory Evoked Potential Long-Latency (LLAEP) to research complex waves P1-N1-P2 and P300 (Cognitive potential) and use speech stimuli presented in the sound field system. Scientific contributions: It is necessary to identify differences between the patterns obtained from children with sensorineural hearing loss and the patterns obtained from normal-hearing children, intending to assist in the selection and fitting of hearing aids, as well as assisting in the rehabilitation of these individuals.(AU)
